Abstract
The invention discloses a self-disassembling device of tower crane, which is characterized in that a self-disassembling arm support device is arranged on an arm support of a tower crane, and a self-disassembling balancing-weight device is arranged on a balancing arm of the tower crane. The self-disassembling arm support device is characterized in that a mast type hoisting frame is arranged under the arm support, the lower ends of two masts are hinged on a variable-amplitude trolley, the upper ends of the two masts are connected through a steel wire, the front end of the front mast is provided with a hanging hook, the rear end of the rear mast is provided with hand chain hoist which is connected through the steel wire, the self-disassembling balancing-weight device is a door beam structure, supporting rods on both sides of the device are spanned on both sides of a balancing-weight, a pulley capable of horizontally moving is arranged on a cross beam, and a plate hook is connected on the pulley. The device enables the tower crane to realize the self-disassembling function, during establishing a tower, the inconvenience brought to the disassembly of the tower because of the limit of construction environment does not need to be considered, thereby the device provides convenience to users. Simultaneously, the cost of hiring a truck type crane and the mounting cost are saved, and the device has better economic benefits.
Description
One, technical field
The invention belongs to the dismantling technology field of tower crane, be specifically related to the stripping assembly of a kind of arm frame of tower crane and counterweight.
Two, background technology
Tower crane all is to install at the scene, original place dismounting again after engineering is finished.Existing tower crane is to carry out ascending, descending joint by stock, Li Ta and tear tower open and will use equipment such as automobile crane, and this has just limited the environment for use of tower machine, and its working space is comparatively spacious, can pass in and out automobile crane.In some cases, can not drop to the dismounting height after the work of tower machine is finished, or the work of tower machine is enclosed in interior of building after finishing, equipment such as automobile crane just can't disassemble it, realize falling saving and tear tower open.
Three, summary of the invention
The self-disassembling device that the purpose of this invention is to provide a kind of tower machine itself makes it can finish self dismounting by other equipment, and can be adapted at the jib and the counterweight of dismounting tower machine in narrower or the osed top scope.The technical solution used in the present invention is: self-disassembling device of tower crane is to install on the jib of tower machine from dismantling boom device, installs on the equilibrium arm of tower machine from dismantling counter weight device.From the dismounting boom device is that a masts type hoist frame is installed below jib, the lower end of two masts is hinged on the amplitude variation trolley, the upper end of two masts is connected by steel rope, and the front end of preceding mast has hoisting cable bonded assembly suspension hook, and the rear end of back mast has by steel rope bonded assembly chain block; From the dismounting counter weight device is the door girder structure, and the strut on its both sides has transversely movable pulley across the both sides of counterweight on the crossbeam, be connected with plate hook through hoisting cable on the pulley.
The present invention has realized from disassembling function tower crane, needn't consider when founding tower because the restriction of construction environment is torn open the inconvenience that tower brings, for the user provides convenience.Save expense and the cost of installation of employing automobile crane simultaneously, had favorable economic benefit.

Five, the specific embodiment
Self-disassembling device of tower crane comprises and is installed in dismantling boom device certainly and being installed in the counter weight device of dismounting certainly on the equilibrium arm 3 on the jib 1.From the dismounting boom device is a masts type hoist frame, and the lower end of preceding mast 5 and back mast 6 all is hinged on the amplitude variation trolley 2 below the jib, and the upper end of two masts 5,6 connects by steel rope 7, at preceding mast 5 front ends hoisting cable 9 bonded assembly suspension hooks 8 is arranged; There are steel rope 10 bonded assembly bottle gouards moved by hands 11 rear end at back mast 6, can walk on jib 1 with luffing dolly 2 after dismantling the boom device installation certainly.During dismantlement work, amplitude variation trolley 2 is moved on to back one of the jib of desiring to dismantle to be saved on the jib, by chain block 11 steel rope 10 is connected jib 1 bottom then, it is motionless to make amplitude variation trolley 2 be fixed on this position, can carry out disassembling section, be hung in the center-of-gravity position that jib winds up with suspension hook 8 and hitcher 16, start lift system jib is dismantled ground.
From the dismounting counter weight device is the door girder structure, and the strut 12 on its both sides has transversely movable pulley 14 across the both sides of counterweight 4 on the crossbeam 13, be connected with plate hook 15 on the pulley 14.During use pulley 14 moved on to the counterweight of desiring to dismantle directly over, and with the bearing pin location, again with bearing pin with plate hook 15 with after clump weight 4 is connected, the startup lift system hangs ground to clump weight 4.The present invention is from dismantling boom device and dismantling the counter weight device work that cooperatively interacts certainly, and when the jib front end was dismantled a joint or two joint jibs, the corresponding clump weight of also will dismantling on the equilibrium arm was in order to avoid cause tower machine centre-of gravity shift.
From dismounting boom device and the lift system of dismantling counter weight device certainly is the lift system that utilizes tower machine itself.When dismounting during jib, the hoisting cable system moved on to from dismantling on the boom device from the jib front end be connected with the suspension hook 8 of mast 5 front ends; And when the dismounting counterweight, again the pulley 14 of hoisting cable through dismantling counter weight device certainly is connected on the plate hook 15.
Claims (2)
1. self-disassembling device of tower crane, it is characterized in that going up installation from dismantling boom device at the jib (1) of tower machine, go up installation from dismantling counter weight device at the equilibrium arm (3) of tower machine, from the dismounting boom device is that a masts type hoist frame is installed below jib (1), the lower end of two masts (5,6) is hinged on the amplitude variation trolley (2), the upper end of two masts is connected by steel rope (7), the front end of preceding mast (5) has hoisting cable (9) bonded assembly suspension hook (8), and the rear end of back mast (6) has by steel rope (10) bonded assembly chain block (11); From the dismounting counter weight device is the door girder structure, and the strut on its both sides (12) has transversely movable pulley (14) across the both sides of counterweight (4) on the crossbeam (13), and pulley (14) is gone up and is connected with plate hook (15) through hoisting cable.
